Anyone have any doings with subsonic .308? Any advantage over .300 blk? I have some 180 gr monolithic copper subsonic going to be in today to sample, didn't know if anyone else has shot any through an ar10 with a can. Supplier states it will not cycle through a simi auto, but my can does over gas alot on that gun. If it doesn't cycle I'm only out 40 rounds.
